It would be nice, but I doubt they will release a Mac version, because they first said they would not support the iPad because it is not a mobile device, and later they said the iPod Touch was no longer supported either.

I need a desktop solution. The internet is spotty at best in China on my iphone and I'd like the option to keep chats going when I'm forced onto my air... like right this moment I'm in a cafe that has wifi and my stupid phone won't connect but my air is on the network just fine and all my conversations have stopped. I'd say the air is a portable device... lazy fellows

I've tried doing it on win and ubuntu for few days without succeeding. If there's someone that has basic knowledge in telnet and programming who want to help me let me know privately. I'll be glad to share my progress so far.

sorry to revive an old thread. but I'm quite interested in knowing whether someone has actually succeeded in porting WhatsApp to the mac? since now more and more people are using it. it would be logical to do it.

I guess you haven't used it. Whatsapp is a messages application (like BBM and iMessage) but its available on all mobile operating systems. so iPhone users can chat with BB users and nokia users, etc...
and its killer feature is that it uses your phone number, not emails or pins, so you dont have to "add" people, as long as you have them on ur contact list, you have them in whatsapp (of course, they should have it too )

iMessage for Mac might convince them to bring out a Mac version as well. Besides group chat functionality iMessage killed whatsapp for me. Actually not quite yet, some of my friends need to get their act together and update their iOS devices.
